Battle of the beauties: Glamour model Rhian Sugden, known for 'sexting' Vernon Kay, will share the house with controversial journalist Samantha Brick, and both were booed on entering tonight

She was quickly followed into the house by former EastEnders star Cheryl – who played Heather Trott – who vowed not to stand for any nonsense from her fellow contestants.

She told host Brian Dowling: 'I've got a few things up my sleeve. I've got a few choice words if they do f**k me off a bit.'

Oh the drama! Soap stars Julie Goodyear and Cheryl Fergison caused hilarity as they successfully followed Big Brother's instructions to cause fights in the first 90 minutes

Arguing already: Cheryl had to pretend that Julie had cheated on her ex behind her back in the outside world, causing her to cry and argue in front of the housemates

As the pair took in their surroundings, they were summoned to the Diary Room and told Big Brother wanted them to be 'formidable drama queens' and turn the show into a “soap opera” for the next 90 minutes.

They were then given earpieces and told they would be given instructions as the show played out and the house would be 'rewarded' if they successfully carried out the task.

Jersey Shore star Mike 'The Situation' Sorrentino was third to enter the house and Cheryl was quickly given her first task – told to take the new addition to one side and reveal she hated Julie because he had an affair with her ex-boyfriend, much to the bemusement of the US star.

Julian Clary – who poked fun at Brian by calling him 'Davina', referring to former host Davina McCall – soon followed them down the stairs, with glamour model Rhian Sugden following entering to the sound of boos shortly afterwards.

Julie's first mission involved telling Rhian she reminded her of her 'favourite barmaid' and warning her to be careful of the men in the house.

MC Harvey 'lied' about his appearance on Celebrity Big Brother.

The drama begins: Dowling introduced all of the housemates and giggles at Julie and Cheryl were told their first secret task to cause 90 minutes of drama

The former So Solid Crew star – who was the sixth person to enter the iconic house tonight – insisted he hadn't taken advice from former bandmate Romeo, who appeared on the show earlier this year because he had only told his mother he was taking part.

Seventh in the house was controversial journalist Samantha Brick – who caused a stir when she claimed she was hated for being beautiful in a famous Daily Mail article printed in April – who was booed by the crowd as soon as she stepped out of the door.

Asked if she thought she would be the best-looking housemate, she laughed and said: 'No, not at all. Every woman is beautiful.'

The Bachelor star Prince Lorenzo Borghese – a member of the Italian noble family the House of Borghese – was then introduced, and before an eighth person could enter, Cheryl Fergison was given another aspect of her secret mission.

Lavish new set: Each star had their turn in front of the crowd and cameras before disappearing inside

The former EastEnders star – who along with Julie Goodyear had been ordered to create a 'soap opera' by following instructions in a hidden ear piece – went to the garden with Harvey in order to tell him Julie had previously had an affair with her ex-boyfriend, something she had earlier been ordered to confide to Mike 'The Situation' Sorrentino.

She broke down in tears as the musician did his best to console and advise her.
